A novel natural insecticide molecule for grain protection

We have isolated a novel bioactive molecule from the roots of Decalepis hamiltonii that shows insecticidal properties against the stored-product insects Sitophilus oryzae, Rhyzopertha dominica and Callosobruchus chinensis by contact bioassay (LC50: 0.033-0.044 mg/cm2). This compound proved effective as a grain protectant against stored product insects of wheat and green gram. The compound is a novel insecticidal molecule and a promising grain protectant of natural origin.
